- A 20-30%
- B 50-60%
- C 70-90% ✓
- D 100%
Correct answer: C. 70-90%
Explanation
Percutaneous Achilles tenotomy is required in approximately 70-90% of idiopathic clubfoot cases treated by the Ponseti method. Tenotomy is performed when the foot achieves sufficient abduction (60-70°) and the equinus deformity persists (dorsiflexion <15-20°). It is a minor procedure done under local anesthesia, followed by a final cast for 3 weeks.
